The present technology relates generally to devices, systems, and methods for reducing the size of a medical device. In particular, some embodiments of the present technology relate to compact crimping devices for reducing a size of prosthetic heart valve devices.

Medical devices, such as stents and prosthetic valve devices, can be introduced into a lumen of a body vessel via percutaneous catheterization techniques. These medical devices may be expandable from a first cross-sectional dimension that allows for percutaneous device delivery to a second cross-sectional dimension at a treatment site. In the expanded state, the medical device has a larger cross-sectional dimension than the catheter used to deliver the medical device. Accordingly, a crimping device is typically used to crimp (i.e., reduce) a cross-sectional dimension of the medical device so that the medical device can be loaded into the catheter and advanced to a treatment location in the body. At the treatment location, the medical device can be removed from the catheter and expanded (e.g., via self-expansion, balloon catheter expansion, or mechanical expansion means) to provide a treatment function.

Prosthetic heart valve devices (e.g., prosthetic mitral valve devices) can have a large cross-sectional dimension in the expanded state relative to other medical devices (e.g., stents) delivered via percutaneous catheterization techniques. For example, some prosthetic mitral valves can have an expanded cross sectional dimension of 1.97 inches or more. It is often desirable to package and store prosthetic heart valve devices in their expanded state until just before implantation into the patient. For example, prosthetic heart valve devices can be stored in a sterile solution up until the time the prosthetic heart valve device is ready to be loaded into a delivery system for implantation. Therefore, it is often desirable to crimp prosthetic heart valve devices in the operating room and only a few minutes before a procedure to implant the prosthetic heart valve device. Such procedures preclude pre-crimping by the manufacturer, and benefit from crimping devices that are highly portable and readily available as a sterile system.

Many aspects of the present disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale. Instead, emphasis is placed on illustrating clearly the principles of the present disclosure. Furthermore, components can be shown as transparent in certain views for clarity of illustration only and not to indicate that the illustrated component is necessarily transparent.

With regard to the terms “distal” and “proximal” within this description, unless otherwise specified, the terms can reference relative positions of portions of a prosthetic valve device and/or an associated delivery device with reference to an operator and/or a location in the vasculature or heart. For example, in referring to a delivery catheter suitable to deliver and position various prosthetic valve devices described herein, “proximal” can refer to a position closer to the operator of the device or an incision into the vasculature, and “distal” can refer to a position that is more distant from the operator of the device or further from the incision along the vasculature (e.g., the end of the catheter).

Overview

FIG. 1 shows an embodiment of a crimping and loading system 10 (“system 10”) for reducing the size of a medical device in accordance with the present technology. In particular, the system 10 can be used to crimp or compact the medical device to enable the medical device to be loaded into a delivery system for percutaneously delivering the medical device to a patient. In some embodiments, the medical device can be a prosthetic heart valve device. More particularly, the medical device can be a mitral valve device for implantation into a native mitral valve and the delivery system can be a delivery system for delivering the mitral valve device to the native mitral valve, such as one or more of the mitral valve devices and/or delivery systems disclosed in (1) International Patent Application No. PCT/US2014/029549, filed Mar. 14, 2014, (2) International Patent Application No. PCT/US2012/061219, filed Oct. 19, 2012, (3) International Patent Application No. PCT/US2012/061215, filed Oct. 19, 2012, (4) International Patent Application No. PCT/US2012/043636, filed Jun. 21, 2012, (5) U.S. patent application Ser. No. 15/490,047, filed Apr. 18, 2017, and (6) U.S. patent application Ser. No. 15/490,008, filed Apr. 18, 2017, each of which is incorporated herein by reference in its entirety.

As shown in FIG. 1, the system 10 includes a crimping device 100, a medical device holder 200 (“holder 200”), a tray 300, and a stand 400. The crimping device 100 includes a plurality of blades (not visible; described in further detail below) that define a channel 115 configured to receive a medical device in an expanded state, and an actuating member 105 operably coupled to the blades. The actuating member 105 can be manipulated by a user to vary or reduce a cross-sectional dimension (e.g., a diameter) of the channel 115 and, thereby, reduce the outer dimension of the medical device positioned within the channel 115. In some embodiments, the holder 200 is releasably coupled to the medical device, and then detachably coupled to an entry side 101 of the crimping device 100 such that the holder 200 positions the medical device appropriately within the channel 115 of the crimping device 100 before and/or during crimping.

As shown in FIG. 1, the crimping device 100 can be positioned at least partially within a reservoir 310 in the tray 300. In some embodiments, the tray 300 includes a plurality of flanges 305 that project into the reservoir 310 and define a recess 315 that is sized and shaped to retain the crimping device 100 such that the channel 115 is positioned within the reservoir 310. In other embodiments, the tray 300 can include different or additional features for retaining and appropriately positioning the crimping device 100 within the tray 300, such as fasteners, interlocking surfaces, and/or other suitable retention features. The reservoir 310 can hold a liquid (e.g., chilled saline) that submerges the channel 115 when the crimping device 100 is positioned within the recess 315. As further shown in FIG. 1, the tray 300 can also include an aperture 320 for receiving a portion of a delivery system 600 therethrough and to facilitate loading the crimped medical device into the delivery system 600. For example, an elongated catheter body 605 and/or delivery capsule 610 of the delivery system 600 can be inserted through the aperture 320 and positioned adjacent to the channel 115 on an exit side 103 of the crimping device 100. In some embodiments, the tray 300 can further include one or more sealing members (not shown) positioned within the aperture 320 to at least partially seal liquid within the reservoir 310 when the delivery system is moved into and out of the reservoir 310. The stand 400 can be positioned to support a portion of the catheter body 605 and/or align the delivery system 600 with the aperture 320 of the tray 300. In other embodiments, the system 10 can include additional components or some of the features may be omitted.

In operation, the crimping device 100 is positioned within the recess 315 of the tray 300. A medical device, such as a prosthetic heart valve device, is releasably attached to the holder 200 while the medical device is in its expanded state (e.g., an unconstrained state), and then the holder 200 is attached to the entry side 101 of the crimping device 100 such that the medical device extends into the channel 115. In some embodiments, the holder 200 is attached to the entry side 101 of the crimping device 100 before the crimping device 100 is positioned within the recess 315 of the tray 300. In some embodiments, the medical device can be packaged with and pre-attached to the holder 200. In some embodiments, the holder 200 is omitted, and the medical device can be placed in the channel 115 by itself and/or releasably attached to another portion of the crimping device 100 to retain the medical device in the channel 115. Before or after the medical device is positioned in the channel 115, the reservoir 310 of the tray 300 can be filled with a liquid (e.g., chilled saline) such that the channel 115 of the crimping device 100 and the medical device positioned therein are submerged in the liquid. Submerging the medical device can keep the medical device chilled as the crimping device 100 acts on the medical device to reduce the outer dimension of the medical device.

When the system 10 is used to facilitate loading of the device into the delivery system 600, a distal portion of the catheter body 605 can be positioned through the aperture 320 such that the delivery capsule 610 at the distal end of the catheter body 605 is positioned at the exit side 103 of the crimping device 100 adjacent the channel 115. In some embodiments, a distal nose cone of the delivery capsule 610 and an elongated central shaft attached thereto are inserted at least partly through the channel 115 and the unconstrained medical device (e.g., toward the entry side 101 of the crimping device 100 beyond a distal end of the medical device). The stand 400 can be positioned to support the catheter body 605 and/or other portions of the delivery system 600 outside of the tray 300, and to align the delivery system 600 with the aperture 320 of the tray 300 and the channel 115 of the crimping device 100.

Once the delivery system 600 and the medical device are properly positioned with respect to the crimping device 100, a user can manipulate the actuating member 105 of the crimping device 100 to reduce the cross-sectional dimension of the channel 115, and thereby reduce the outer dimension of the medical device (i.e., “crimp” the medical device). In some embodiments, the medical device is crimped to accommodate sizing of the delivery capsule 610 for implanting the medical device using a minimally invasive procedure. In some embodiments, reducing the cross-sectional dimension of the channel 115 disengages the holder 200 from the medical device such that the medical device is no longer attached to the holder 200 to allow for subsequent removal of the medical device from the channel 115 (e.g., via the exit side 103 or the entry side 101 of the crimping device 100).

Once the medical device has been crimped, the medical device can be loaded into the delivery system 600 for subsequent delivery to a patient. For example, a portion of the delivery system 600 can be configured to engage the medical device and pull the crimped medical device into the delivery capsule 610 and/or the catheter body 605. In some embodiments, a piston device of the delivery system 600 engages with features of the medical device, and is then retracted to pull the medical device into the delivery capsule 610. In some embodiments, the channel 115 of the crimping device 100 has a generally funnel-like shape in which the diameter of the channel 115 decreases along an axis from the entry side 101 to the exit side 103 (i.e., away from the holder 200 and toward the delivery capsule 610. In such embodiments, pulling the medical device into the delivery capsule 610 can further crimp a portion of the medical device as the medical device is pulled from a wider-diameter portion of the channel 115 and through a narrower-diameter portion of the channel 115. In some embodiments, the medical device is pulled into the delivery system 600 while submerged in the liquid within the reservoir 310. This is expected to inhibit air pockets or air bubbles from forming in the delivery system 600 as the medical device is loaded. Once the medical device is loaded in the delivery system 600, the delivery system 600 can be withdrawn from the tray 300 and subsequently used to implant the medical device in a patient. In some embodiments, the system 10 is configured to be a completely disposable system. Accordingly, the various components of the system 10, including the crimping device 100, can be disposed of (as compared to being cleaned for subsequent re-use) after the medical device is loaded into the delivery system. By making the system 10 disposable, the system 10 can be provided as a new, sterile environment prior to each procedure.

Selected Embodiments of Crimping Devices, Medical Device Holders, and Associated Methods

FIGS. 2 and 3 are isometric views of the crimping device 100 of FIG. 1 illustrating the crimping device 100 in a first position with the channel 115 having a first cross-sectional dimension (FIG. 2) and in a second position with the channel 115 having a second cross-sectional dimension (FIG. 3). FIG. 4 is an isometric partially exploded view of the crimping device 100 of FIG. 2 (i.e., showing the crimping device 100 in the first position). In some embodiments, the first and second cross-sectional dimensions are a maximum and a minimum cross-sectional dimension, respectively. The crimping device 100 includes a frame 110, a plurality of movable blades 140 arranged circumferentially within the frame 110 to define the channel 115 having a central axis 107 extending therethrough.

Referring to FIG. 4, the frame 110 can include a first plate 120 having a plurality of first slots 122 extending through portions of the first plate 120, and a second plate 130 having a plurality of second slots 132 extending through portions of the second plate 130 (collectively referred to as “plates 120, 130”). The crimping device 100 further includes a first movable member 160 and a second movable member 170 (collectively “movable members 160, 170”) that are movable (e.g., rotatable) with respect to the first and second plates 120 and 130. For example, the movable members 160, 170 can be configured to rotate about the central axis 107 of the channel 115. The first movable member 160 is positioned between the blades 140 and the first plate 120, and the first movable member 160 includes a plurality of third slots 162 extending through portions of the first movable member 160. Similarly, the second movable member 170 is positioned between the blades 140 and the second plate 130, and the second movable member 170 includes a plurality of fourth slots 172 extending through portions of the second movable member 170. Portions of the first slots 122 can be aligned with portions of the third slots 162, and portions of the second slots 132 can be aligned with portions of the fourth slots 172. In some embodiments, the first and second slots 122 and 132 (collectively referred to as “slots 122, 132”) and the third and fourth slots 162 and 172 (collectively referred to as “slots 162, 172”) are reflectively symmetric about a plane extending perpendicularly to the central axis 107 of the channel 115.

Each blade 140 can include a pin 142 that projects from a portion of the blade 140 spaced apart from the central axis 107 (e.g., an outer portion of the blade 140). At the exit side 103 of the crimping device 100, each pin 142 extends through one of the first slots 122 of the first plate 120 and a corresponding one of the third slots 162 of the first movable member 160, and at the entry side 101 of the crimping device 100 each pin 142 extends through one of the second slots 132 and a corresponding one of the fourth slots 172 of the second movable member 170. Accordingly, the quantity of slots 122, 132, 162, 172 on each of the plates 120, 130 and the movable members 160, 170 can correspond to the quantity of blades 140. In operation, a user can manipulate the actuating member 105 to rotate, slide, or otherwise move the first and second movable members 160 and 170 relative to the first and second plates 120 and 130. This drives the pins 142 along paths defined by corresponding slots 122, 132, 162, 172, thereby driving the blades 140 radially inward to decrease the cross-sectional dimension of the channel 115 (FIG. 3). The radially inward movement of the blades 140 acts on an outer surface of a medical device (e.g., a prosthetic heart valve device) positioned within the channel 115 and, thereby, reduces the outer cross-sectional dimension (e.g., diameter) of the medical device to fit within a delivery capsule (e.g., the delivery capsule 610 of FIG. 1). In some embodiments, the second plate 130 and the second movable member 170 are omitted such that the relative movement of the first plate 120 and the first movable member 160 alone drive the inward motion of the blades 140.

The plates 120, 130 can have a generally rectangular shape such that the frame 110 has a generally rectangular cross-section. In other embodiments, the plates 120, 130 can have other shapes such as, for example, circular, hexagonal, polygonal, etc., and can have different shapes from one another. For example, when the plates 120, 130 have a circular shape, the frame 110 can include a stabilizing base region. In some embodiments, the plates 120, 130 can be internal components positioned within an outer housing that defines the frame 110. The frame 110 can have a shape configured to fit snugly within the recess 315 (FIG. 1) of the tray 300. The actuating member 105 can be positioned on an upper surface 112 (FIG. 2) of the frame 110 such that it is accessibly to a user during a crimping procedure. In other embodiments, the actuating member 105 may be positioned elsewhere on the frame 110, or may be an electric motor instead of a manual actuator. As shown in FIG. 4, the plates 120, 130 are stationary relative to the movable members 160, 170. In some embodiments, the first plate 120 is movable relative to the first movable member 160 and/or the second plate 130 is movable relative to the second movable member 170 to drive the blades 140 radially inward. For example, manipulating the actuating member 105 can rotate the first plate 120 in an opposite direction as the first movable member 160.

The first and second slots 122 and 132 can each define a straight path extending radially away from the central axis of the channel 115. As shown in FIG. 4, each plate 120, 130 can include twelve slots 122, 132 spaced at equal intervals around the central axis 107 of the channel 115. However, in some embodiments, each plate 120, 130 can include fewer than or more than twelve slots (e.g., six slots, eight slots, fourteen slots, etc.) depending on the quantity of blades 140, and/or the slots 122, 132 can be arranged in other configurations and can have different shapes. For example, one or more of the slots 122, 132 can define a generally arcuate or other path. As illustrated in FIG. 4, the second slots 132 can have generally similar features to the first slots 122. In other embodiments, the second slots 132 can have a different number and/or have a different configuration, shape, etc. from the first slots 122.

The third slots 162 on the first movable member 160 can each define an arcuate or angled path having a first end 163a and a second end 163b spaced radially closer to the central axis of the channel 115 than the first end 163a. In some embodiments, the first movable member 160 includes twelve arcuate slots 162 spaced apart from each other at equal intervals around the central axis 107 of the channel 115. In other embodiments, the plurality of third slots 162 can include fewer than or more than twelve slots (e.g., eight slots) depending on the quantity of blades 140, and can be arranged in other configurations and can have different shapes. For example, the third slots 162 can define a generally straight path, or could have a concave portion that faces radially outward from the central axis of the channel 115. Although partly obscured in FIG. 4, the fourth slots 172 can have generally similar features to the third slots 162. In some embodiments, the slots 162, 172 are reflectively symmetric about a plane extending perpendicularly to the central axis 107 of the channel 115. In other embodiments, the slots 162, 172 can each comprise a different number of slots, and/or have different configurations, shapes, etc. from one another. Moreover, as shown in FIG. 4, the slots 162, 172 can be longer than the slots 122, 132 in the plates 120, 130. In some embodiments, the slots 162, 172 extend radially the same or a substantially similar distance as the slots 122, 132.

The first through fourth slots 122 132, 162, 172 define a path of movement for the pins 142. For example, the first and second slots 122 and 132 can be sized and shaped to maintain the position of the individual blades 140 relative to each other, and the third and fourth slots 162 and 172 can be sized and shaped to drive the blades 140 radially inward or outward. Accordingly, movement of the pins 142 along the slot paths causes the blades 140 to slide relative to each other and to move radially inward or outward. For example, movement of the first movable member 160 relative to the first plate 120 drives the pins 142 along the path defined by the third slots 162 of the first movable member 160 and constrained by the path of the first slots 122 of the first plate 120. Similarly, movement of the second movable member 170 relative to the second plate 130 drives the pins 142 along the path defined by the fourth slots 172 of the second movable member 170 and constrained by the path of the second slots 132 of the second plate 130. When the pins 142 are in an initial or first pin position (FIG. 2), the blades 140 are arranged such that the channel 115 has a maximum cross-sectional dimension (e.g., diameter), and the pins 142 are positioned at a radially outer end 123a (FIG. 2) of the first slots 122 and a radially outer end 162a (FIG. 4) of the third slots 162. When the pins 142 are in a final or second pin position (FIG. 3), the pins 142 are positioned at a radially inner end 123b (FIG. 3) of the first slots 122 and a radially inner end 162b (FIG. 4) of the third slots 162, and the channel 115 has a minimum cross-sectional dimension. Accordingly, the pins 142 can move between the first and second pin positions to reduce and expand the cross-sectional dimension of the channel 115. In other embodiments, the pins 142 can be positioned at different locations (e.g., positioned at an intermediate location) along the first slots 122 when in the first and/or second pin configuration. When the medical device is positioned within the channel 115, driving the pins 142 radially inward can reduce a cross-sectional dimension (e.g., diameter) of the medical device. In some embodiments, such as embodiments including twelve blades 140, the blades 140 are configured to reduce an outer diameter of a prosthetic heart valve device from about 1.67 inches (42.42 mm) to 0.4 inch (10.16 mm) or less. For example, the blades 140 can be configured to completely close the channel 115 in the second pin position (i.e., a cross-sectional dimension of the channel 115 is zero). As another example, in embodiments including eight blades 140, the blades 140 can be arranged such that the channel 115 has a maximum outer diameter of about 1.3 inches (33.02 mm) and can reduce the diameter of the channel 115 to 0.4 inch (10.16 mm) or less. The maximum and minimum cross-sectional dimensions of the channel 115 can depend on the quantity of blades 140, the size and shape of the blades 140, the locations of the pins 142 on the blades 140, and/or the travel path of the blades 140 as defined by the slots 122, 132, 162, 172.

As shown in FIG. 4, the second plate 130 includes a plurality of first connective features 133 and a plurality of second connective features 135. The first connective features 133 can be holes, flanged surfaces, and/or other attachment mechanisms configured to releasably couple the medical device holder 200 (FIG. 1) to the second plate 120 of the frame 110. The second connective features 135 are configured to provide an attachment mechanism for forming the frame 110 (e.g., connecting the first plate 120 to the second plate 130). As shown, the second connective features 135 can be hooks or fasteners shaped to mate with corresponding holes 125 on the first plate 120. In some embodiments, the second connective features 135 permit the frame 110 of the crimping device 100 to be taken apart to, for example, permit cleaning of the individual components within the frame (e.g., the blades 140 and movable members 160, 170). In some embodiments, the first and second plates 120 and 130 can be fixedly attached to each other via bonding, welding, and/or other attachment methods.

As further shown in FIG. 4, the crimping device 100 can also include an actuator device 150 operably coupled to the first and second movable members 160 and 170, and configured to move the first and second movable members 160, 170 relative to the first and second plates 120 and 130. In some embodiments, as shown in FIG. 4, the actuator device 150 includes the actuating member 105 coupled to a threaded shaft 152 and a connector 154 having a threaded shaft 156 extending therethrough. The connector 154 couples to portions of the first and second movable members 160, 170. Turning the actuating member 105 rotates the threaded shaft 152 about a longitudinal axis of the threaded shaft 152, which in turn moves the connector 154 along the length of the threaded shaft 152. Movement of the connector 154 moves the first and second movable members 160, 170, thereby driving the pins 142 inward or outward along the paths defined by the slots 122, 132, 162, 172 of the plates 120, 130 and the movable members 160, 170. For example, a user can turn the actuating member 105 in a first direction to cause the connector 104 to move downwards (i.e., towards the bottom of the page) in order to rotate the first and second movable members 160, 170 clockwise about the central axis 107 of the channel 115. Clockwise rotation of the first and second movable members 160, 170 can drive the pins 142 inward along the combined paths of the first and third slots 122, 162 and second and fourth slots 132, 172 to reduce the cross-sectional dimension of the channel 115. Turning the actuating member 105 in the opposite direction can rotate the movable members 160, 170 in the counterclockwise direction to drive the pins 142 outward along the combined paths of the first and third slots 122, 162 and second and fourth slots 132, 172 to increase the cross-sectional dimension of the channel 115. In some embodiments, the actuator device 150 can be configured to rotate the blades 140 in the opposite directions to effectuate device compression. The actuator device 150 illustrated in FIG. 4 provides for continuous (e.g., rather than stepwise) compression of a medical device placed within the channel 115 of the crimping device 100, and can have a relatively smaller footprint as compared to other types of actuators.

In some embodiments, the actuator device 150 can comprise a different mechanism to drive movement of the movable members 160, 170, and/or the actuator device 150 can be coupled to the movable members 160, 170 in a different manner. For example, in some embodiments, the actuator device 150 can comprise a lever coupled to the movable members 160, 170. In other embodiments, the movable members 160, 170 can be configured to slide (i.e., rather than rotate) relative to the plates 120, 130. In such embodiments, the actuator device 150 may comprise a handle or other gripping mechanism for sliding the movable members 160, 170. In still other embodiments, the actuator device 150 may include an electric motor configured to move the movable members 160, 170.

FIG. 5 is an isometric view of one of the blades 140 of the crimping device 100 (FIGS. 1-4). Each blade 140 can include a first end portion 141a, a second end portion 141b, a first side 143a, and a second side 143b. The pin 142 of each blade 140 can include a first pin portion 142a projecting from the first side 143a of the blade 140 (e.g., toward the entry side 101 of the crimping device 100 of FIGS. 1-4), and a second pin portion 142b projecting from the second side 143b of the blade 140 (e.g., toward the exist side 103 of the crimping device 100 of FIGS. 1-4). The first pin portion 142a and the second pin portion 142b (collectively referred to as “pin portions 142a, 142b”) can be a single component (e.g., a single shaft) extending through and/or integrally formed with the blade 140, or the pin portions 142a, 142b can be separate pin components that project from either side of the blade 140. In some embodiments, some or all of the blades 140 can include only the first pin portion 142a or only the second pin portion 142b. As shown in FIG. 5, the pin portions 142a, 142b project from the second end portion 141b of the blade 140. When the blade 140 is positioned within the crimping device 100, the second end portion 141b is spaced apart from and radially farther from the central axis 107 of the channel 115 than the first end portion 141a. Accordingly, the pin portions 142a, 142b project from a radially outer portion of the blade 140. Compared to a blade with a pin positioned at a central or more radially inward position of the blade, this radially outward positioning of the pin 142 requires less actuation (i.e., the pin 142 need not be driven as far) to produce an equal amount of inward movement of the blade 140. As a result, the overall size of the crimping device 100 is reduced while still maintaining a sufficiently large crimping range (e.g., the range between a minimum and maximum cross-sectional dimension of the channel 115) to accommodate the sizing of a medical device in an expanded state and the sizing of a delivery system (e.g., a delivery capsule).

As further shown in FIG. 5, the blade 140 includes an inner surface 146a and an outer surface 146b. In general, the inner and outer surfaces 146a and 146b are configured to enable adjacent blades 140 to slide relative to one another and to define a shape of the channel 115 of the crimping device 100. More specifically, the inner surface 146a can be generally sloped along an axis extending between the first and second sides 143a and 143b of the blade 140 (e.g., along the central axis 107 of the channel 115 shown in FIGS. 2-4). The outer surface 146b can have a portion that is generally shaped to match the shape of the inner surface 146a of an adjacent blade 140, and is configured to slide against the inner surface 146a of an adjacent blade 140 as the pin portions 142a, 142b are actuated (e.g., driven radially inward or outward along the slots 122, 132 and slots 162, 172).

A portion of the inner surfaces 146a (e.g., a portion not covered by the outer surface 146b of an adjacent blade 140) of the blades 140 collectively define the channel 115 of the crimping device 100. When the blades 140 with a sloped inner surface 146a are arranged circumferentially, the channel 115 can have a generally funnel-like shape (e.g., as shown in FIG. 8). That is, the channel 115 can have a larger cross-sectional dimension closer to the second sides 143b of the blades 140 (e.g., proximate to the second plate 130 at the entry side 101 of the crimping device 100) than the first sides 143a of the blades 140 (e.g., proximate the first plate 120 at the exit side 103 of the crimping device). In other embodiments, the inner and outer surfaces 146a, 146b of the blade 140 can have other shapes or arrangements. For example, the inner surfaces 146a of each blade can have a wedge-like shape such that the channel 115 has a constant cross-sectional dimension along the central axis of the channel 115. In yet other embodiments, the blades 140 can generally have any other shape or configuration so as to form a channel 115 with a varying cross-sectional dimension along the central axis 107 of the channel 115. In some embodiments, the inner and/or outer surfaces 146a, 146b of the blade 140 can include one or more grooves, slots, holes, etc. These features can reduce the weight of the blade 140 to thereby increase the portability of the crimping device 100, without affecting the function or strength of the crimping device 100.

In some embodiments of the present technology, the crimping device 100 can omit one or more of the components described above with reference to FIGS. 2-5. For example, the crimping device 100 can include only one of the movable members 160, 170, and each blade 140 may include only one of the pin portions 142a or 142b to drive the blades 140 inward to reduce the size of a medical device. However, redundancy of the two movable members 160, 170 and the two plates 120, 130 at the first and second sides 101 and 103 of the crimping device 100 effectively supports each blade 140 at both the first and second side 143a, 143b of the blade 140. Including two movable members 160, 170 can also decrease the amount of force required to actuate the blades 140, and can facilitate at least substantially equal distribution of the actuating force across the blades 140 between the first and second sides 143a, 143b. In some embodiments, the crimping device 100 can include fewer than twelve blades (e.g., four blades, five blades, six blades, eight blades, etc.) or more than twelve blades (e.g., sixteen blades, twenty blades, etc.), and the quantity of slots 122, 132, 162, 172 of the movable members 160, 170 and the plates 120, 130 can be modified to correspond to the number of blades 140.

Each of the components described above with reference to FIGS. 2-5 can be made from the same or different materials, such as metals, polymers, plastic, composites, combinations thereof, and/or other materials. The components of the crimping device 100 can be manufactured using suitable processes, such as, for example, three-dimensional printing, injection molding, and/or other processes for supporting and compressing a medical device during a crimping procedure. In some embodiments, each component is made from a suitable plastic or polymer such that the system is completely disposable and able to be manufactured at a relatively low cost. In some embodiments, some of the components illustrated herein as individual components can be integrally formed together or otherwise combined.

In use, the crimping device 100 can provide a compact, yet efficient mechanism for reducing the size of a prosthetic heart valve device or other medical device. The slots 122, 132 of the plates 120, 130 and the slots 162, 172 of the movable members 160, 170 define paths for the pins 142 that slide the blades 140 radially inward relative to each other to reduce the diameter of the channel 115. This radially inward force is continuous along the surfaces of the blades 140 contacting the medical device within the channel 115, and therefore provides continuous compression of the medical device. As such, the continuous compression allows the user to pause or terminate the crimping procedure at any time (i.e., not just at the maximum and minimum diameters of the channel 115). Further, the funnel-like shape of the channel 115 provided by the blade shape allows portions of the medical device to be compressed more than other portions during inward movement of the blades. For example, a larger portion of the medical device may be positioned in the larger portion of the channel 115 (e.g., toward the entry side 101 of the crimping device 100) and not undergo as much compression as the portion of the medical device positioned in the smaller portion of the channel 115 (e.g., toward the exit side 103 of the crimping device 100). This can inhibit the compressive crimping forces from moving the medical device laterally toward the entry side 101 of the crimping device 100 and help retain the medical device within the channel 115 during crimping. In addition, the position of the pins 142 on the outer portions of the blades 140 reduces the length of the pin travel path necessary for inward movement of the blades 140 to achieve the desired crimping range. For example, the pins 142 can travel a distance of 0.26 inch (6.604 mm) to reduce the channel diameter from about 1.3 inches to 0.4 inch or less. Thus, the arrangement of the pins 142, the blades 140, the movable members 160, 170, and the plates 120, 130, in conjunction with the actuator device 150, allows the crimping device 100 to have a compact size that can easily be moved by a clinician to and from a sterile field, while still providing for a large crimping range suitable for reducing the size of prosthetic heart valves to allow for percutaneous delivery of the device.

FIG. 6 is an isometric view showing the medical device holder 200 (“holder 200”) configured in accordance with an embodiment of the present technology and coupled to an exemplary medical device 500. In some embodiments as shown in FIG. 6, the medical device 500 is a valve support for use with a prosthetic heart valve device. The holder 200 includes a base 202 having a first side 203a, a second side 203b, and an opening 205 extending therebetween. The base 202 can include a plurality of connectors 201 on the second side 203b and configured to removably couple the holder 200 to the crimping device 100 (e.g., to the connective features 113 of the second plate 130 of FIGS. 2-4). As shown in FIG. 6, the base 202 can have a generally annular shape including a radially outer surface 209a and a radially inner surface 209b, both extending between the first and second sides 203a, 203b. The outer surface 209a can include a plurality of grooves 207 and/or ridges to make the holder 200 easy to grip and manipulate, even while submerged during the crimping process. The holder 200 further includes a plurality of first fingers 206 and a plurality of second fingers 208 (collectively “fingers 206, 208”) projecting from the base 202 and arranged circumferentially around a central axis extending through the opening 205 of the base 202. The fingers 206, 208 are configured to engage at least a portion of the medical device 500 to hold the medical device 500 within the channel 115 of the crimping device 100 (FIGS. 2-4) during at least an initial portion of a crimping procedure.

As shown in FIG. 6, the first fingers 206 can be spaced around the central axis of the opening 205 to engage the medical device 500 at more than one point around a circumference of the medical device 500. The first fingers 206 include a first portion 206a extending radially inward from the inner surface 209b of the base 202 toward the central axis of the opening 205, a second portion 206b extending from the first portion 206a and away from the second side 203b of the base 202, a third portion 206c extending from the second portion 206b and radially inward toward the central axis of the opening 205, and a fourth portion 206d configured to engage the medical device 500. The fourth portion 206d can include an index feature 206e shaped to engage a portion of the medical device 500. For example, as shown in FIG. 6, the medical device 500 can be a stent-device including a frame 580 comprising a plurality of frame cells 582. Each frame cell 582 can have a hexagonal shape and comprise a pair of first struts 583, a pair of second struts 584, and a pair of third struts 585. Each of the first struts 583 can extend from an end of the second struts 584, and pairs of the first struts 583 can be connected together to form V-struts 586. At least some of the V-struts 586 at an end portion of the frame 580 can define an apex 587. As shown, the index features 206e can have a generally V-like shape to engage (e.g., mate with) an individual V-strut 586 of the medical device 500. In other embodiments, the medical device 500 and/or the first fingers 206 can have other suitable shapes that enable the first fingers 206 to engage a portion of the medical device 500. For example, the medical device 500 may be a stent device having frame cells 582 with a rectangular, sinusoidal, triangular, polygonal, or other shape, and the index features 206e can have a corresponding shape and arrangement that mates with or fits within a portion of the frame cells 582. In some embodiments, the first fingers 206 are configured to engage with the atrial end of a valve support of a prosthetic mitral valve device and/or other atrial portions of the prosthetic mitral valve device. In some embodiments, the first fingers 206 are configured to engage with the ventricular side of the valve support and/or other ventricular portions of the prosthetic mitral valve device.

In some embodiments, the first fingers 206 are flexible such that they bend radially inward or outward in response to external forces applied to the first fingers 206. For example, when the holder 200 is not attached to the medical device 500, the fourth portions 206d of the first fingers 206 can be positioned a distance away from the central axis of the opening 205 that is slightly greater than a cross-sectional dimension of the medical device 500. To attach the medical device 500, the first fingers 206 can be bent radially inward until the fourth portions 206d of the first fingers 206 are within the medical device 500, and then released. Accordingly, the index features 206e of the first fingers 206 can press against (e.g., the first fingers 206 are slightly radially biased outward against) a radially interior side of the medical device 500 to hold or grip the medical device 500. The index features 206e can prevent the medical device 500 from slipping off of the holder 200 when no other forces are applied to the first fingers 206. When the holder 200 is attached to the crimping device 100 (FIGS. 1-4), the blades 140 can press down on the first fingers 206 as the channel 115 decreases in size, thereby causing the first fingers 206 to flex inwardly and release the medical device 500 from the holder 200 for subsequent loading into the delivery system 600 (FIG. 1).

The second fingers 208 can each include a first portion 208a extending radially inward from the inner surface 209b of the base 202 toward the central axis of the opening 205, a second portion 208b extending from the first portion 208a and away from the second side 203b of the base 202, and a third portion 206c extending from the second portion 208b and radially inward toward the central axis of the opening 205. Notably, the first portion 208a of each second finger 208 is longer than the first portion 206a of each first finger 206. The second portions 206b of the first fingers 206 are therefore positioned radially farther from the central axis of the opening 205 than the second portions 208b of the second fingers 208. As shown, the third portions 208c of the second fingers 208 can be shaped and positioned to receive the apexes 587 of the medical device 500. The second fingers 208 can therefore provide additional support for holding the medical device 500 in place. In some embodiments, the holder 200 can include fingers 206, 208 with other shapes, arrangements, quantities, etc., suitable for holding the medical device 500 in place. For example, the holder 200 may comprise more or less than the twelve fingers 206, 208 shown in FIG. 6 (e.g., more or less than three first fingers 206 and more or less than nine second fingers 208). In some embodiments, the holder 200 includes only the first fingers 206 or only the second fingers 208.

FIGS. 7 and 8 are an isometric view and a cross-sectional side view, respectively, illustrating the holder 200 of FIG. 6 coupled to the crimping device 100 shown in FIGS. 2-4. For ease of illustration, the medical device 500 is not shown in FIGS. 7 and 8. Referring first to FIG. 7, the holder 200 can be removably coupled to the entry side 101 of the crimping device 100 via the second plate 130 of the frame 110. More specifically, the connectors 201 (shown in FIG. 6) of the holder 200 can connect to the first connective features 133 disposed on the frame 110. In some embodiments, the connectors 201 are at least one of hooks, fasteners, clips, locking features, etc. that engage (e.g., mate with) the first connective features 133 to removably secure the holder 200 to the crimping device 100. In some embodiments, the connectors 201 are inserted into the connective features 113, and the holder 200 is rotated to secure the holder 200 in place. Once secured, the central axis of the opening 205 of the holder 200 can be generally aligned with the central axis 107 of the channel 115 of the crimping device 100. By aligning the central axes of the crimping device 100 and holder 200, the medical device 500 can be evenly spaced with respect to the blades 140 within the channel 115 before the medical device 500 is crimped to facilitate generally symmetric radial compression of the medical device 500.

As shown in FIG. 8, the fingers 206, 208 of the holder 200 can project at least partly into the channel 115 of the crimping device 100. Accordingly, the fingers 206, 208 of the holder 200 can hold the medical device 500 (FIG. 6) in a position that is fully within the channel 115. FIG. 8 further shows an embodiment in which the channel 115 has a generally funnel-like shape in which a cross-sectional dimension (e.g., diameter) of the channel 115 decreases along the central axis 107 moving from the entry side 101 of the crimping device 100 to the exit side 103 of the crimping device 100.

Referring to FIGS. 6-8 together, to crimp the medical device 500, the actuating member 105 is manipulated as described above to reduce the diameter of the channel 115. As the diameter of the channel 115 decreases, portions of the blades 140 can contact portions of the first fingers 206 and/or portions of the second fingers 208 that are within the channel 115. Specifically, the blades 140 first contact the second portions 206b of the first fingers 206 because they are positioned radially farther from the central axis of the channel 115 than the second portions 208b (FIG. 6) of the second fingers 208. As the diameter of the channel 115 is further decreased, the blades 140 exert an inward force against the second fingers 208 that bends the fingers 208 radially inward and causes the fourth portions 206d of the first fingers 206 to disengage from the medical device 500. The blades 140 do not contact the first fingers 206 until after contacting the second fingers 208 because the second portions 208b of the second fingers 208 are positioned radially closer to the central axis 107 of the channel 115 than the second portions 206b of the first fingers 206. Therefore, after the first fingers 206 disengage from the medical device 500, the third portions 208c of the second fingers 208 can still engage and support a portion of the medical device 500 (e.g., the apexes 587). In some embodiments, the second fingers 208 can inhibit the medical device 500 from moving laterally (e.g., translation between the opposing plates 120, 130) while the medical device 500 is crimped. For example, the second fingers 208 can counteract the tendency of the medical device 500 to move laterally toward the entry side 101 of the crimping device 100 as a result of non-uniform compression of the medical device 500 caused by the funnel-like shape of the channel 115.

In some embodiments, the diameter of the channel 115 can be decreased to a small enough diameter to disengage the holder 200 from the medical device 500 (e.g., disengage the first fingers 206), but maintain a large diameter such that the fingers 206, 208 positioned within the medical device 500 do not interfere with the crimping of the medical device 500. For example, the holder 200 and the crimping device 100 can be configured such that the holder 200: (i) holds (e.g., is engaged with and grips) the medical device 500 when the channel 115 of the crimping device 100 has a maximum diameter (e.g., the first position shown FIG. 2), and (ii) is disengaged from the medical device 500 when the channel 115 of the crimping device 100 has a minimum diameter (e.g., the second position shown FIG. 3). In some embodiments, the holder 200 can be removed from the crimping device 100 after the holder 200 disengages from the medical device 500. In such embodiments, the diameter of the channel 115 can then be further decreased to further crimp the medical device 500.

Selected Embodiments of Trays for Receiving a Crimping Device

FIG. 9 is a top view of the tray 300 of the crimping and loading system 10 of FIG. 1 configured in accordance with embodiments the present technology. The tray 300 can be formed using a thermoforming process and/or other suitable tray forming processes. As shown, the interior walls of the tray 300 define the reservoir 310 for holding a liquid (e.g., chilled saline). The reservoir 310 can include a first portion 312, a second portion 314, and a third portion 316. The first portion 312 can be sized and shaped to receive the crimping device 100 (FIGS. 1-4) with the entry side 101 or the exit side 103 facing down against a bottom surface of the tray 300 prior to use (e.g., during storage and/or shipping). The second portion 314 of the reservoir 310 is defined by the flanges 305 of the tray 300 and includes the recess 315 that is configured to retain the crimping device 100 (FIGS. 1-4) in a stable upright position during the crimping procedure. In some embodiments, the tray 300 includes a slot for introducing the liquid into the reservoir 310. The slot can be configured to allow liquid to enter the reservoir 310 in a non-turbulent manner, which is expected to inhibit air bubbles from forming in portions of the tray 300 or the crimping device 100. For example, in some embodiments, the slot provides a liquid flow path into the first portion 312 of the reservoir 310.

The third portion 316 of the reservoir 310 can be positioned at the exit side 103 of the crimping device 100 (e.g., as shown in FIG. 1), and can provide a region in which the crimped medical device can be loaded into a delivery system (e.g., the delivery system of FIG. 1). In some embodiments, the third portion 316 of the reservoir 310 can also provide an area to visualize the channel 115 of the crimping device 100 and/or portions of the delivery system positioned adjacent the crimping device 100 (FIG. 1) during device loading. For example, the tray 300 can include slanted sidewalls (identified individually as a first slanted sidewall 317a and a second slanted sidewall 317b; referred to collectively as “slanted sidewalls 317”) on which one or more mirrors can be placed to provide alternate views of the crimping device 100 (FIGS. 1-4) and/or the delivery system. In some embodiments, the tray 300 has a generally flat lower surface in the third portion 316 with a mirror disposed on the lower surface to provide for visualization during device loading. The third portion 316 of the reservoir 310 can also be shaped to receive the stand 400 (FIG. 1) so that that the stand 400 can be positioned in the third portion 316 prior to use (e.g., during storage and/or shipping). Accordingly, in some embodiments, each component of the system 10 (FIG. 1) can be securely positioned within dedicated portions of the tray 300 for shipping and storage. The system 10 (FIG. 1) can therefore be provided to a physician in a streamlined and sterile manner.

As further shown in FIG. 9, the walls of the tray 300 further includes the aperture 320 for receiving a portion of a delivery system (e.g., the delivery system 600 of FIG. 1) therethrough, and one or more grooves (identified individually as a first groove 319a and a second groove 319b; referred to collectively as “grooves 319”) positioned on either side the aperture 320. The grooves 319 can be configured to receive a dam member (not pictured) for sealing the reservoir 310 and preventing liquid from escaping through the aperture 320. In some embodiments, a portion of a suitable delivery system can puncture the dam members positioned within the grooves 319 in order to position the portion of the delivery system adjacent the crimping device 100 (FIG. 1). In some embodiments, the tray 300 can include valve and/or sealing device that is positioned on a sidewall of the tray 300 (e.g., in the aperture 320 or other hole) and in fluid communication with the reservoir 310. The valve and/or sealing device can fluidically seal liquid in the reservoir 310 before, during, and/or after a delivery system (e.g., the delivery system 600 of FIG. 1) has been moved therethrough. For example, a valve (e.g., a cross-slit valve, a one-way check valve, etc.) can be housed within a grommet (e.g., a molded silicone grommet) that is positioned in the hole in the sidewall of the tray 300 to at least partially prevent liquid from leaking from the reservoir 310 when the delivery system is moved into and out of the valve member. In other embodiments, the tray 300 can include other configurations of valves and/or sealing devices to seal liquid within the reservoir 310, while still allowing access to the reservoir 310 from a sidewall of the tray 300 for device loading or adjustment.
